Sample integrated Fourier transform (SIFT): a novel real-time process
W.E. Pelton, Tong Ta, N. Yossakda, Pochang Hsu · 2002
A zero-latency Fourier transform algorithm and an efficient implementation are presented. 64-point complex FT simulated: 8 mW, 49 mm/sup 2/, 12.8 /spl mu/sec. 1024-point FT proposed: 500 mW, 32 mm/sup 2/, 3.2 /spl mu/sec.
